CORD-FASTENING- HOOK.

Application filed April 6,

To all 'w/mm'ir may concern Be it known that 1, WILLIAM L. M. Ro- BIDOUX. a subject of the King of England. residing at Pawtucket. in the county of Prov idence and State of Rhode Island, have invented certain new and useful Improvements in Cord-Fastening Hooks. of which the following is a specincation.

This invention relates to improvements in cord-fastening hooks adapted for use a lacing fastener for shoes and also for fastoning the ends of cords or lines such as clothes lines. and other cords and lines. and the object of this invention is to provide such a hook having a shank portion with a base-flange and guide flange and a headmember. the guide flange having a portion extending beyond the periphery of the flange less than one diameter of the cord whereby the drawing of a second turn of the cord about the shank of the hook forces the first turn to ride up over the guide flange and cross the second turn to automatically bind that part of the second turn at the point of crossing.

ii ith these and other objects in view. the invention consists of certain novel features of construction, as will more fully de scribed. and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a front view showing a portion of a shoe with the ends of the lacing secured by being locked in my improved fastening hook.

Figure 2 is an enlarged top view of n improved hook.

. Figure 3 is a side elevation of the hook showing a tubular shank adapted to be ap plied to a shoe-upper for receiving and se curing the end of the lacing.

Figure 4 is a side elevation of an enlarged fastening hook adapted more particularly to be applied to a suitable base such as the side of a house and the like to which the end of a clothes line may be attached.

Figure 5 is a section on line 55 of Fig-- ure at. looking in the direction of the arrow and showing the counter-sunk holes formed in the base-flange to receive the attaching screws.

Figure 6 is a top view sectioned on line 6-6 of Figure 5, showing the cord as applied to the hook one portion of the cord Specification of Letters Patent. Pgyptgn t gd Jung 13 1922,

being bound to the hook by the passing of another portion of the cord tl'iereover.

Figure 7 is a perspective view showing one portion of the cord as crossing and binding another portion thereof. the crossing portion being engaged by the notch in the guide-flange.

It is found in practice to be of advantage to be able to produce a lacing-hook or cordfastening hook of simple and practical construction that will secure and bind the end of a cord or lacing therein by simply winding the part twice around the hook and. drawing the end taut. which construction is of advantage either as a hook to be applied to shoes for securing the end of a lacing. or as a hook of a larger size to be applied to a suitable base to which the end of a cord line may be fastened by simply taking second turn about the hook and drawing the same taut, and the following is a detailed description of one means by which this result may be accomplished To accomplish the fastening of cord to the hook automatically the hook must be set so that the angle of lead oi the cord as shown in Figures 1 and 6. will be such as to cause the first coil or turn of the cord to slide into the space beneath the head and be drawn up against the bridge portion thereof upon being forced or raised out of the lower groove by the drawing or laying of the second turn of the cord thereinto.

With reference to the drawings, 10 designates the shank portion of the hook which is provided with a base-flange l1, and at the outer end of this shank is mounted a guideiiange 12 spaced above the flange 11 substantially one diameter of the cord which the hook is designed to receive.

This guide-flange is provided with a rearwardly-extending neck portion 13 from which rises a bridge-member 14E supporting a head 15 which extends back over the guideflange being spaced approximately one diameter of the cord above said flange.

The guide-flange 12 is preferably elongated on its sides as at 16 providing hook-shaped edges 17 having its rear edge undercut or notched as at 18 forming a recess for the reception of a portion of the cord 19. This recess or undercut portion being preferably formed on opposite sides of the post so as to permit the hook to be used either as a right at the front of the hook as at 20 or that portion opposite the bridge i l, whereby the first turn is caused to normally lie in the s* ace between the base-tlange and the guide-flange until the second turn is made, which second turn is caused to crowd the first turn oi? the cord and toree it up over the narrow lip 20 into the space between the guide-flange and the head and a continued. pulling or slipping ol the cord carries the raised part oi? the cord outwardly to be drawn against the bridge 14L- and over into the notch 18, which notch serves to assist in locking the cord at the point of crossing to positively prevent the free end from becoming withdrawn by any tension applied to the opposite end. thereof.

The device is extremely simple and practical in construction and effective in its action and by its use when properly set relative to the lead of the cord, it is only necessary to pass the cord twice around the shank of the fastener and by drawing tightly on the tree end of the second turn it will automatically force the first turn out ot its original position to cross the second turn and so securely lock the end in the hook.

The foregoing description is directed solely towards the construction illustrated, but I desire it to he understood that I reserve the privilege ot resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms ot the appended claims.

I claim:

1.. A cord-fastening hook comprising a shank having a base-flange, a guide-flange on said shank spaced trom said base-flange substantially one diameter of the cord and having a portion extending beyond the periphery of said shank less than one diameter of the cord, and a head connected to and spaced from said guide flange substantially one diameter oi the cord whereby the drawing of a second turnot the cord about said shank forces the first turn to ride up over the guide-flange and across the second turn to automatically bind the second turn at the point of crossing.

2. A cord-fastening hook comprising a shank having a base-flange, a guide-flange on said shank spaced from said base-flange sul'istantially one diameter of the cord and having a portion extending beyond the periphery of said shank less than one diameter of the cord and provided with a notch on its side edge, and a head member connected to the rear of said guide-flange by a bridge portion whereby the drawing of a second turn ot the cord about said shank forces the first turn to ride up over said guide-flange into said notch to lie against said bridge and cross the second turn to automatically bind that part of the second turn at the point of crossing.

In testimony whereof I atlix my signaturev WILLIAM L. M. ROBIDOUX.
